Hey, When SETI@Home comes back up, will this mean that nearly ALL the workunits (or a very substantial proportion of them) be returned after their notional dealine and therefore be worthless?

How do you know that? Have you read it somewhere or do you just think that will be the case? I have not read it anywhere other than as speculation.

Live long and crunch.

And proud of it!

I can only hope John is right. One of the machines in my farm was down for
about a week before I noticed it and rebooted. I rebooted the machine in
question on 8/20/05, and the project went down on 8/23/05, so I have about 75
results to report that are past the deadline, but would have been reported
on time if the project was up and running. I'd hate to see all those results
go to waste. At least the results from my other 16 machines will still be
valid if they can be uploaded within a few days.

It's only speculation from my soap box, but I think they might allow the units - providing a grace period per'se, but realistically we'll have to wait and see.

My earliest WU deadline is 3rd Sep, and I've had no work to crunch for some days now, so I'm hoping the SETI@Home gang can bring the ship back online soon.

Live long and crunch.

When a result is reported late, its sibling files could be in one of three states: (1) not yet validated because units were reissued or results haven't matched, (2) already validated but not yet deleted, or (3) long gone.

In the first case, SETI appears to accept the late result and validate it along with the others, granting credit in the process.

In the second case, the sender doesn't get any credit, but the result file is cleaned up by the system.

In the third case, the result file becomes an antique... slowing the entire project down to a crawl and spawning hundreds of angry Message Board posts :-)

Assuming for the sake of argument no special accomodation is made when the project comes back on-line, result files will start pouring in. The work unit can't be validated until a certain number of result files return, even if every one of them is late. Thus, credit should not be an issue since everyone is going to be late.

The problem is if the system delcares all of those results overdue and re-issues them as soon as downloads resume. This would represent a huge amount of wasted computing effort... the work is already out there.

I hope that the project keeps the reissue-due-to-expired-results process held up for a few days after everything gets rolling again. Hopefully this would not prevent the validator from reissuing work units in cases where the result files are inconsistent with each other.

Damn, I read the original post all wrong....damn.

Because Matt, or was it John VII, said the same thing the other day in one of the answers they gave. Matt or John said that what will happen is that some of use will have the 4th unit and if the other 3 have already been validated and then delted we will create all new "antique" files and get no credit. If we are part of the orginal pre-validation set we will be fine.

I think we will just have to wait till it is back online to see what will happen to those units. They can change the deadline easily for new work going out, don't know how easy it is for work that was already assigned a due date. Have not seen anything offical about that.

From the technical news, linked from the SETI home page:

As well, those who fear their results will arrive past deadline to be counted should fear not. As long as the respective workunits are still in the database, credit will be granted. We'll hold off running db_purge for a while, so people can return their work after a long outage without missing any deadlines.

Well this info from the Technical News page did not hold up to expectation:

Result 99112474 of WU 21844661 just got 0.00 credits. It wasn'gt even checked for correctness: Validate state Result was reported too late to validate

Hermes, that WU was due back on the 10th, well before the Great SETI Outage.

I hope this is True. I have 10 Work Units that were Due Yesterday 8/30/2005. I finished them way last Week but could not turn them in due to the Outage. They are now listed as No Reply with 0.00 Seconds Computer time.

You are looking at the wrong workunit. His was issued on the 11th and would have been due by the 25th. According to the technical news it should have been validated but was not due to being late. Check it out.

Whoops, so I was. Sorry about that.

In 11 More Hours I am going to have another 20 Work Units go to waste (Timed Out) unless I am allowed to Upload my Results. Worse, I will be away from my Desk for 9 of these hours and I am on Dial Up. I think I just lost 30 Work Units worth about 750 Credits (At 25 Each) plus alot of Wasted Computer time.

Once more... Read what is says, Timcom99.

Any unit still in the database will get credit. Even if it is returned after the deadline. English is your native language, it can't be that hard to read something you quoted yourself?

The units showing in the database as 0.00 credit will get updated once they are in (uploaded & reported by you) and validated.

---

I will also state that WUs that do get 0 credit, if returned late, and they had a quorum will probably get credit later. They have a program that goes through and fixes this. Since they promised credit in the Technical News, and this issue has happened before, they can fix it again.

Hermes got stuck in an odd situation. He had been given a WU that was reissued twice. The other person got his WU turned in before Hermes did. The other person's WU completed the quorum, therefore the WU was validated, thus closed.

I'm afraid, in this case, Hermes lost out due to the outage. In most cases, however, I do believe that the late WU's will still get credit, as discussed in the Tech News.
